Nutritional Evaluation on AO Transgenic High Phytase Maize
摘要
Abstract
[Objective] To evaluate the nutrition of AO transgenic high phytase maize.[Method] National standard method was used to determine the main nutrients in both genetically modified and parental corn.100 weaning SD rats divided into 5 groups and feeding for 28 days,and the nutritional,hematological and biochemical indicators before and after test,and also the protein efficacy ratio were compared.[Result] The main nutrients in both genetically modified and parental corn were similar.The average weight gain and average daily gain of test groups were all lower than control group (P ＜ 0.05),and average daily gain of group A was higher than group B (P ＜ 0.05).The white blood cell count both of male rats,and female rates in group A and B were all lower than control group (P ＜ 0.05),AST of male rats in group B and D,CRE of group A were all higher than control group (P ＜ 0.05),and the AST of male rats in group C were lower than group D (P ＜ 0.05).The PER of all the test groups were lower than control group (P ＜ 0.05),and the PER and corrected PER of genetically modified and parental corn were no difference (P ＞ 0.05).[Conclusion] The AO transgenic high phytase maize has substantial equivalence as its non-GM maize,and this type maize is safe from the view of nutritional point.关键词
